Here Bulbasaur uses "Leaf Cutter" is that just a mis-translation of Razor Leaf? Or does the manga have its own moves :O
He uses Razor Leaf later so I don't think it's the same move
It's a translation error.
Since the Japanese name for Razor Leaf translates as 'Leaf Cutter', this is likely to be a translation error.
I've read the manga before and it's full of little mistakes like this, so I wouldn't be surprised about it.
